A classic in anyone’s workwear wardrobe, the short sleeve men’s shirt will never go out of fashion, and this two pack offers twice as much style and, thanks to our Easy to Iron finish, plenty of practicality. Particularly useful in the warmer months, they’re made with a lightweight, breathable material and feature a handy breast pocket. Fashioned in a traditional checked design with a classic collar and button-down front, these regular fit shirts for men are perfect for everyday use.
